    Just thinking: it would "only" take 4 PEMs, 4 Tesla motors (the electricity-to-motion converters, not the company!) and 12kWh of A123's (which can discharge at 60C) installed in a Veyron to match the Veyron's ICE and get to 250mph. Oh, and replace the gearbox with a 1:4 or so gear ratio on each wheel.

    Considering all that, it's quite a radical racecar they used to get to 307mph, just 23% above the Veyron's top speed.

    12kWh is 43200 kWseconds
    If you pull 720kW you only get 60 seconds of juice.
    Its going to be tough getting to 250 mph in 60 seconds, especially without a transmission.

    However on the flip side: you can make a much more aerodynamic car than the Veyron, because you arent turning 70%-80% of the energy you consume into heat - heat you need to dump via radiators.
